That would work but its not vary expandable. Try doing that for five or six
loops. The proposed solution is just a lot cleaner, even in the two loop case.

Or how about doing that with something like:

char[] arr;
int j=0, i, skip;

do
{
foreach(inout i, c; arr[j..$])
if(‘ ' == c)
break;

// do something and continue
j+=(i+skip);
}while(i != arr.length)
